Double notifications for an SMS with mirror service

So, without the mirror service, the SMS pushes work fine, except I have to clear the notifications on all of my devices if they are all open. On top of that, the device that pushed the SMS to all the others doesn't have it's SMS notification cleared, either.

I thought I found a fix when I enabled the mirror service. I chose to mirror my Textra App from the SMS pushing device. On any of the other devices, when I clear the incoming notification, it clears all the others...

Except for that double notification from Join that will not clear and, again, if I have all the other devices open, the notifications just pile up.

Any solutions for me?
